GASSING-MAGHINE FOR YARN AND THREAD.

Specification of Letters Patent.

Patented Jan. '7, 1908 Application filed May 25,1906- Serial No. 318.781.

T 0 all whom it may concern:

Be it known that I, Josnrn HIGGINSON, Jr., a subject of the King of Great Britain and Ireland, residing at Sovereign forks, Stockport, in the county of Chester, England, have invented new and useful Improvements in Gassing-Machines for Yarn or Llhread, of which the following is a specificaion.

This invention relates to the burners of gassing machines for yarn orthread, and my carry away the dirt or dust and products of combustion coming from the thread and from the flame and so prevent the atmosphere of the room in which the machine is installed from being vitiated.

Heretofore attempts have been made to collect and suck away the dirt or dust and the products of combustion coming from the yarn and from the flame by placing a hood or the like above or adjacent to the burner. The movement of the yarn, however, and drafts produced by other causes act to carry much of the dust and products of com- V bustion into the room.

The nventlon conslsts 1n pro ecting the flame irom a burner lnto a tube and causmg the yarn to pass along said tube, means being provided for exhausting the contents of the tube and inducing a current of cool air along one end of the tube or an extension of the tube.

Referring now to the accompanying drawings;Figure 1 is a sectional elevation of a burner, porcelain tube, thread guides, and other accessories, constructed and arranged in one convenient form according to my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a cross section on the line A B of Fig. 1. Fig. 4 is a view of a percelain tube similar to that shown at Fig. 1, but illustrating a modified arrangement of burner. Fig. 5 is an end elevation of the porcelain tube and burner shown in Fig. 4. Fig. 6 is a diagrammatic view showing the manner in which the thread is guided oil a cop and through a tube of refractory material. Fig. 7 is a diagrammatic view showing an alternative arrangement of tube, burner, etc. Fig. 8 is a diagrammatic view, partly a section, showing another alternative arrangement of tube, burner and other accessories, and Fig. 9 is a cross sectional view of the same, the section being taken on the line C D of Fig. 8. Fig. 10 is a cross sectional view showing another alternative arrangement of tube and burner. Fig. 11 shows a further modification.

Referring in the first place to Figs. 1, 2 and 3, a is a tube which conveys a mixture of gas and air to the j et burner b, The pipe a is supplied with a mixture of air and gas, which mixture is preferably arranged to have too small a proportion of air to be an explosive mixture. The burner is arranged to give a long flame and to project this long flame into the hole c, in the porcelain tube (Z. This porcelain tube is inclosed in a metal tube 6. The porcelain tube is formed with a slit and the metal tube with a slit g. To the metal tube a is attached a metal tube 71 which I shall call the exhausting tube. This exhausting tube contains a porcelain liner 7c. The interior of this liner is in communication with the interior of the porcelain tube 61 and is also in communication with the interior of a main exhausting flue m. A machine is provided with a number of burners, each furnished with its procelain tube and other accessories. All the tubes h, on one side of the machine, communicate with the main exhausting flue m. The thread coming from the cop a (see Fig. 6) passes through an eye 0 and another eye 1), and then doscends and passes round a pulley q, through the porcelain tube, over the pulley 1', and then to the bobbin or tube on which it is be ing wound. The pulley q is mounted on the upper end of an arm 8, which is rigidly secured on a shaft t. The pulley 'r is carried on the end of an arm u which is also rigidly secured on the shaft 25. This shaft is adapted to be given an angular movement by means of a crank 11 which is connected by means of a link 10 with a lever a; pivoted about a fixed fulcrum y. The lever a; is adapted to be operated by hand so as to swivel the arm 8 from the position shown in full lines in Fig. 2 to the position shown in dotted lines and vice versa and to swivel the arm a correspondingly. hen the arms are in the positions shown by full lines, the thread is stretched through the hole 0 in the porcelain tube and, when the arm 8 is in the position shown by dotted lines, and the arm a is in the corresponding position, the thread is clear of the porcelain tube. The thread enters and leaves the porcelain tube byway of the slits g and f in the metal tube e and the porcelain tube.

I may if desired close the slit f in the porcelain tube after the thread is inserted within it. This maybe done in a convenient manner by providing the arm 8 with a U-sh aped stud 2, which is adapted to engage with a projection .2 formed on the porcelain tube. When the arm 8 is being pushed to the right in Fig. 2, the projection z is acted on by the stud. 2, and pushed to the right also, thereby partially rotating theporcelain tube (Z and closing the slit f, as'the metal tube a does not rotate with the porcelain tube. When the thread is bieng withdrawn from the porcelain tube, the motion of the arm 8 causes the stud 2 to engage with the projection z and uncover the slit I produce a draft in the main exhausting flue m by any suitable means so as to suck the products of combustion and the dirt and charred matter which comes off the thread down the tube h into the main exhausting flue. This main exhausting flue is arranged to discharge its contents in any convenient place. The contents may be discharged into water or the solid matter precipitated onto a traveling band which may carry it away.

The porcelain tube (1 is shown in Fig. 1 as being continued to the right of the exhausting tube h. This is to enable the thread to be cooled and subjected to acurrent of cool air before it leaves the tube. Air is drawn to the exhausting tube h from both ends of the porcelain tube (1. The left hand end of the tube (1 in Fig. 1 is entirely filled with hot air and other gas and the right hand end entirely filled with cold air. The thread therefore after being subjected to the action of the flame is drawn through cool air before it leaves the tube. This is a most important matter and constitutes an essential part of my invention. The thread in passing along the right hand portion of the porcelain tube d is moved in a contrary direction to the current of cold air which acts to remove charred matter and dirt from it. I may if desired restrict the hole in the right hand portion of the porcelain tube d so as to give a very narrow opening for the passage of air and produce a very strong draft at that point.

Referring now to Figs. 4 and 5, an alternative arrangement is here shown in which aflat burner 3 is employed which gives a flame which is short in the direction of efliux of the gas from the burner but is long in a direction at right angles to this. A slot 4 is formed in the porcelain tube and a corresponding slot 5 is cut in the enveloping metal tube to ad mit this burner. The burner and the pulleys g and 1* are so arranged with respect to the porcelain tube that the thread as far as practicable passes through the hottest part of the flame. In other respects the apparatus shown in Figs. 4 and 5 resembles that shown in Figs. 1, 2 and 3 and the action is in substance the same in the two cases.

Referring now to Fig. 6, a horizontal ar rangement of tube is here shown diagrammatically, a jet burner 12 being employed therewith. of porcelain tube is shown.

Figs. 8 and 9 show an arrangement of vertical porcelain tube, with a fiat burner 3.

Fig. 10 shows another alternative arrangement. In this case one slit serves to admit the burner and to admit the thread. The dotted line 6 represents the plane of motion of the thread in being inserted into and withdrawn from the porcelain tube. The arrangement shown in Fig. 10 may be employed both when the porcelain tube is horizontal and when it is arranged vertically.

Fig. 11 shows the combination with a jet burner 12 of a metal tube made up of a T piece 6 and a straight part c as shown.

I may provide the exhausting tube It with a jacket as shown at 7 in Fig. 1. In this jacket I may heat the air supply to the burner or I may employ the jacket for holding water for cooling the exhausting tube. Y

By means of my invention the products obtained from the combustion of the gas and from the combustion or partial combustion of the yarn are completely or almost completely drawn away and do not mingle with the atmosphere of the room. Moreover the yarn is subjected to the cleansing action of cold air after being subjected to the action of the burner. Two or more threads may if desired be passed in parallel through the same porcelain tube or one thread may be passed in series through the same tube two or more times.

Although I have spoken of a tube constructed of porcelain, I may employ any suitable refractory material. This tube may if desired be made in two or more parts.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In gassing machines for yarn or thread, the combination of a singeing burner for the said yarn or thread, a tube forming a conduit longitudinally through which the said yarn or thread travels while being acted on by the flame from the said burner, and a suction or exhaustion connection opening directly into the said tube, substantially as described.

2. In gassing machines for yarn or thread, the combination of a singeing burner for the said yarn or thread, a tube open at each end forming a conduit longitudinally through which the said yarn or thread travelswhile being acted on by the flame from said burner, and a suction or exhaustion connection opening directly into the said tube at a point between its ends, substantially as described.

3. In gassing machines for yarn or thread, the combination of a singeing burner for the said yarn or thread, a tube open at each end forming a conduit longitudinally through In Fig. 7 a vertical arrangement i said yarn or thread, a tube open at each end forming a conduit longitudinally through which the said yarn or thread travels while 'being acted on by the flame from the said burner, a suction or exhaustion connection opening directly into the said tube at a point between its ends, means for passing the yarn or thread into the interior of the tube and supporting guides for the yarn or thread as it travels through the tube, substantially as described.

5. In gassing machines for yarn or thread, the combination of a singeing burner for the said yarn or thread, a tube open at each end forming a conduit longitudinally through which the said. yarn or thread travels while being acted on by the flame from the said burner, a suction or exhaustion connection opening directly into the said tube at a point between its ends, a jacket for the said connection, means for passing the yarn or thread into the interior of the tube and supporting guides for the yarn or thread as it travels through the tube, substantially as described.

6. In gassing machines for yarn or thread, the combination of an open ended tube provided with a lateral aperture for the admission and withdrawal otthe yarn or thread and having a suction or exhaustion connection opening directly therein, a liner for the said tube having a lateral aperture corresponding with the like aperture in the tube, means for imparting a rotary movement to the liner relatively to the tube, and a burner projecting its flame into the tube, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
